I need use remote debug in our project, however just some experience in Weblogic were found from internet. After my investigation, I got some experience about using Eclipse remote debug RCP.
There are two important parameters for jvm. And we must launch remote java app with those two parameters.
-Xdebug //tells jvm starting with debug mode
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 //transport=dt_socket represents communication with socket, address=1044 represents that the port number is 1044
Then there are 3 steps in local env:
1.import source code into eclipse's project
2.Debug-Remote Java Application, see attachement as a sample
3.insert breakpoint,

update:
a simpler way:
-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8000
